TO ALL PERSONS TO WHOM THESE PRESENTS MAY COME:

Be it known that I, JAMES BROWN, of Pawtucket, in the county of Providence, and State of Rhode Island, have inventedI an Improved Bearing for Speeder-Pliers; and I do hereby declare the same to bc fully'fdescribedy in the following specification, and represented in the accompany-ing drawings, of which- Figure 1 is a top view.

-Figure 2, a longitudinal section. v

Figure 3, a transverse section of a flier-rail with my invention applied thereto.

Figure 4 is e. top view of the bearing as separated from the rail.

The said bearing is intended to receive and support the nose or upper journal of a spindle-flier.

In the drawings, A denotes the flier-rail, it being formed with a female screw, a, cut in it, to receive the male screw of the {lier-bearing B. The said hearing consists of a tube, c, having an annular trough or channel, d, extended around its lower half, in manner as represented. It valso has a. male screw, b, cut or formed -on its upper half. i Two holes, ef, made with the rail A, onV opposite sides of the screw b, lead into the channel d. The rail A is provided on its upper surface with a cover, C, so applied to it as to be capable of being turned laterally on a pin, in order to either cover or uncover the said holes. A

When oil is being poured into one of the holes for the purpose of supplying the ,trough with a quantity of such oil, the air of the trough, displaced by the oil,swill flow out 'of the hole. u

Between the said two holes there is disposed within the trough, and in one-half thereof, a packing, h, of felt, brother proper absorbent material, it being arranged to cover an eduction-passage, t', leading from the trough d, at or near its bottom, into the bore of the tube c. Y l

When the trough Z is supplied with oil, a small portion thereoi` from time to time will leak through the packing t into the passage z', and will nd its way through it to the inner surface of the bre of the bearing B, and while the flier-neck may be therein, such oil will lubricate the contiguous surfaces of such neck and the bearing.' The top of the trough constitutes a shoulder, to arrest the upward movement of the screw b, and by being borne against the lower surface of the rail A, will cause' the trough to be so covered by such rail as to prevent dust from entering the trough.

I am fully aware of the inventions described in the United States patents, Nos. 30,937, 34,221, 44,988, and 45,752. Although the spindle-bearingsdescribed in such patents, orin some one or more of thenihave a trough or oil-chamber to extend' around and concentrically withthe bore or space for reception of the spindle, and such trough has two inlets and one or more cduction-passages, and contains a packing, as is the case with my Speeder-flier bearing, yet in neither of the said inventions so-patented do we find the bearing provided with a male screw to screw up into the rail;A nor do we find the rail provided with ta female screw to receive the said male screw; nor do we find in either of the said patents theoil-trough of the bearing, as arranged underneath the rail, and open at top, so that the raill may serve as a cap to the trough; nor do we find the oil-supply and air-exit holes made in the rail; nor do we nd the packing arranged so as to cover the eduction-holeV only, without covering the inner ends of the oil-supply and airoutlct`holes.

My arrangement of vthe packing renders the trough capable of holding Aa larger quantity of oil than it would were the packing t'o extend entirely around it. Therefore it will be seen that while there are some features common to my Speeder-bearing, and the others, as hereinbefore referred to, there are others of value and importance in mine not found in t'hose described in such patents.

What, therefore, I claim as my invention or improvement, is as follows:

I claim the within-described arrangement of the confining-screws a I1, the tube c, the' rail A, ,and the oiltrough d, placed underneath the rail, the'screws by such arrangement beingwithin the rail, and the oil-trough being below, and covered by it, in manner as specified.

I also claim thc arrangement of the confining-screws a ZJ, the tube c,.thc rail A, provided with oil and airducts ef, the oil-trough cl, and the oil-duct z', substantially ,as described.

JAMES BROWN.
